Abstract : The report presents a revision of Dr. Robert E. Nickell's 'Stress Wave Analysis in Layered Thermoviscoelastic Materials by the Extended Ritz Method' computer code listed in Volume II, Rohm and Haas Technical Report S-175. The revised code uses tape storage in place of directly addressable disk storage and is presented in a form usable by most computers with standard FORTRAN compilers. A user's manual (operating instructions) is included as are the input data and results of a typical example problem. (Author)
